8 Claims.

The present invention relates to an improved form of thread processingapparatus. More particularly, the invention pertains to a novel meansfor use in the manufacture of doubled and twisted thread, yarn, cord,and the like, hereinafter referred to generally as cord."

One of the important objects of the present invention is to provide animproved form of device which is adapted to be applied to conventionaldoubler-twister apparatus for introducing a definite predeterminedtension on the composite cord formed by the doubling and twistingoperation in the course of which a plurality of individual threads ofnatural or synthetic origin are Joined to form a cord and then twistedtogether.

It is a further object of the present invention to provide a mechanismwhich will enable the production of an improved cord characterized by amore uniform twist and gauge.

, It is a still further object of the present invention to provide anapparatus which is capable oi? manufacturing a finished cord on whichall of the loose and projecting fibers of the several component threadsare laid in substantially parallel alignment, thereby producing acomposite cord having a smooth finish.

It is another and still further object or the present invention toafford a means capable of operable association with a conventionaldoublertwiste'r apparatus which will apply heat for the drying andburnishing of a chemically treated composited cord.

Other objects and advantages of the present invention will becomeapparent as the following detailed description of one form ofinstallation illustrated in the accompanying drawings and embodying theprinciples of the present invention proceeds.

The device of the invention is particularly advantageously adapted to beemployed in combination with conventional forms of doubling and twistingapparatus. Such apparatus is capable of handling a large number ofindividual thread supply packages, each of which supplies a singlethread, and for joining with other similar threads from adjacent seriesof supply packages to form a composite cord. Conventionaldoubler-twister apparatus embodies a plurality of cord-forming unitsarranged in spaced generally parallel relation extending longitudinallyof the machine as a. whole.

Figure 1 represents a partial end elevation of a typical form oidoubler-twister apparatus with which the teachings of the presentinvention are particularly advantageously adapted to be embroken away.Figure 3 pioyed. Figure 2 is an enlarged front elevation of theapparatus of the invention with parts is an elevation of the apparatusof Figure 2 as seen from the line 3-4 therein. Figure 4 is a sectionalview taken along the line 4-4 in Figure 2. Figure 5 represents afragmentary front elevation of the apparatus of the inventioncorresponding generally to Figure 2.

In Figure 1 of the drawingathe reference numeral I designates generallya doubler-twister apparatus to which the cord processing device of theinvention has been applied. The doubler-twister apparatus 4 is providedwith a frame 2 on whichs mounted a spindle support 3 which'carries aplurality of spindles 4 and guides 5 disposed in spaced, parallelrelation in a substantially horizontal plane.

Each of the spindles 4 carries a supply spool 6 for providing a threadend i to be incorporated into a composite cord in the course of theoperation of the doubler-twister apparatus. The several threads througha gathering guide it which serves to ar range them in generally parallelrelation to form,

the cord 9. The cord 9 next passes over and in contact with the surfaceof a dip roll it supported by a longitudinally extending freelyrotatably mounted shaft ii. The dip roll it is disposed in a supply ofprocessing liquor contained in a trough it which is supported from theframe 2 by a supporting bracket i3.

After leaving the dip roll ill, the composite cord 9 is directed aboutthe under side or a positively driven roll i l, around an idler roll 18,and under a second driven roll 15. This arrangement of the positivelydriven rolls I 4 and ii in combination with the. idler roll i6 insuresapositive, uniform feed of the cord to the subsequent twistingoperation. The cord 9 next passes over a driven burnishing roll H, thefunction of which will be explained in greater detail hereinafter, to aguide eye I! which directs the cord to a traveler I! mounted upon a ring20 on the ring rail 2i and finally to the collecting spool 22.

The build-up of the package of cord 9 on the collecting spool 22 isachieved in a conventional manner by the" reciprocation of the ring rail2| in combination with theaction of the traveler I9 as it traverses acircular path about the ring 20.-

The collecting spool 22 is simultaneously driven at a high speed ofrotation by a pulley 23 which is actuated by a belt or dip drive 24. Thecollecting spool 22 is disengageably attached to the pulley 23 which isin turn mounted upon a stub shaft 25 1 pass from the supply spools i 3disposed in a bearing support 29. The fixed rail 21 carries a pluralityof the stub shafts 25 and bearing supports 29 disposed in spacedrelation along the longitudinal dimension of the machine. The fixed rail21 is supported from the frame 2 of the machine as by means of a framemounting bracket 28.

The cord p ocessing apparatus of the present invention, as more clearlyillustrated in Figures- 2 to 4, inclusive, of the drawings, serves toprovide a compressing and burnishing effect upon the cord 9 as it passesover the burnishing roll H in its path of travel from the driven rollsl4 and I! of the twister feed mechanism to the collecting spool 22. Theshafts 29 and 39, upon which are mounted the driven rolls l4 and I5,respectively, are supported at one end thereof by a suitable bearingbracket 3| mounted upon the frame 2 of the doubler-twister apparatus iand at the other end thereof in bearings 32 on an end plate 33 formingpart of the frame 2.

The ends of the shafts 29 and 39 extend slightly beyond the end plate33, thereby enabling the shaft 29 to carry a sprocket 34 and chain of adriving mechanism which is actuated by the prime mover (not shown) ofthe doubler-twister appa- V ratus i. A spur gear 36, secured to theshaft 29, transmits power to a spur gear 31 mounted upon the end of theshaft 39 through an idler gear 33 freely rotatably mounted upon a stud39 secured to the end plate 33. V

' A suitable housing 49- may be employed to enclose all of the drivingapparatus at the one end of the doubler-twister apparatus i and disposedbeyond the end plate 33 of the frame 2 thereof. It will be understoodthat by virtue of the gearing relation embodying the several gears 39,31, and 38, the driven rolls [4 and I comprising the twister feedmechanism be rotated in the same direction. The driven rolls i4 and i5will insure a positive feed of the cord 9 to the twisting apparatus andthe collecting spool 22 disposed therebelow. The idler roll itassociated with the driven rolls i4 and i5 is advantageously weighted toinsure constant frictional engagement between the cord 9 and the drivenrolls i4 and IS in the operation of the apparatus.

The burnishing roll I1 is supported by a shaft 4| mounted in a bearingbracket 42 on the frame 2 at one end thereof, and a boss 43 in the endplate 33 at the other. A pair of spaced brackets 44 are arranged toadjustably support the weighted idler roll IE to enable it to be raisedand lowered with respect to the driven rolls i4 and I5 to facilitate thethreading up of the apparatus. A single idler roll it is provided foreach individual cord 9 at each position on the machine extending fromend to end thereof.

A portion of the shaft 29 extending through the bearing bracket 3irotatably supporting the driven rolls I4 and i5 carries a single pulley45. A dual idler pulley 46 embodies a pair of pulley segments 41 and 48of different diameters and vis rotatably supported by bearing bracket49. The

drive for pulley 46 is achieved by means of a belt 50 which is trainedover the pulley 45 and pulley segment 41. x

The pulley 46 in turn drives a smaller single pulley 5! by means of belt52 which contacts the larger of the pulley segments 48. The pulley ii ismounted upon the end of the shaft 4| supporting and driving theburnishing r011 i'l. By virtue of the pulley sizes employed intransmitting the drive from the shaft 29 to the shaft 4|, the'burnishing roll I1 is driven at a speed somewhat higher than the rate ofdelivery of the cord from the twister feed mechanism embodying theseveral driven rolls l4, l3 and idler roll It will be readily understoodthat any desired conventional form of drive can be substituted for thatshown and described. Moreover, any desired driving relationship can beachieved b changing pulley sizes, gearing, and the like. It iscontemplated by the present invention to rotate the burnishing roll I'Iat a speed such that it will exert a slight tension upon the cord 9being delivered from the twister feed mechanism embodying the rolls I4,I! and I6, thereby permitting a slight slippage of the cord 9 withrespect to the surface of the burnishing roll IT.

The slipping action of the cord 9 on the roll 7 i1 causes the cord toroll upon itself and, thus.

pressed into the body of the cord as it is subsequently twisted. Toprevent excessive axial pro- 'gression of the cord, a restraining collar53 is positioned on the outer periphery of the burnishing' roll itadjacent the path of contact of the cord upon the surface of the rolland defining a more or less restricted area over which,the cord may movealong the roll.

The use of the collars 53, one for each cord 9, on the burnishing rollll serves to increase the effective surface of contact with thetraveling cord 9. It will be understood that when the cord 9, isdisposed in contact with one face of" the collar 53, as well as the rollH, the burnishing action thereon is produced both by the edge of thecollar and by the portion of the roll surface adjacent thereto.

If desired, heat may be supplied to the burnishing roll IT to facilitatethe smoothing and drying effect upon the cord 9. This heating step maybe accomplished in any one of several different ways of which the methodillustrated in Figure 5 of the drawings is but one. In the illustratedmodification of the invention, a burnishing roll 54 is provided with aperforated hollow shaft 55 for introducing steam from a suitable supplysource 56 to the interior of the roll. The steam supply 59 is connectedto the shaft 55 as by means of piping 5] and coupling 59. Thus, the roll54 may readily be uniformly heated to any desired temperature toeffectively dry and burnish the cord 9.

Other modifications may be made in the apparatus of the inventionwithout in any way departing from the spiritor scope of the invention.pulley drive for the burnishing roll might advantageously be supplantedby a gear drive unit. Moreover, any form of heating of the housing issatisfactory.

While in accordance with-the patent statutes one best known embodimentof the invention has been illustrated and described in .detail, it is tobe particularly understood that the invention is v not limited theretoor thereby, but that the inventive scope is defined in the appendedclaims.
